1. Which of the following examples is a correctly punctuated compound sentence?

• A. Condors are protected by laws, but many people fear they will soon become extinct.
• B. Asian elephants, cheetahs, and tigers are all in danger of extinction.
• C. Some efforts are being made to protect animals and more people are behind this initiative.
• D. Most hunters don't kill endangered species, but some don't care if it's unlawful.

Correct answer: A

Rationale: Option A presents a correctly punctuated compound sentence. It consists of two independent clauses 'Condors are protected by laws' and 'many people fear they will soon become extinct,' which are appropriately joined by a comma and the coordinating conjunction 'but.' In contrast, in option B, the sentence only lists items without independent clauses. Option C combines phrases without independent clauses, and Option D incorrectly uses a comma before the coordinating conjunction 'but' without an independent clause following it.

2. Which of the following salt solutions is most likely to conduct electricity well?

• A. A saturated solution
• B. A concentrated solution of a strong electrolyte
• C. A dilute solution of a weak acid
• D. A mixture of a neutral compound and water

Correct answer: B

Rationale: A concentrated solution of a strong electrolyte is most likely to conduct electricity well. Strong electrolytes completely dissociate into ions in solution, allowing for the flow of electric current. This high concentration of ions in the solution enhances its conductivity, making it a better conductor compared to other options. A saturated solution, although containing dissolved ions, may not have a high enough concentration to conduct electricity effectively. A dilute solution of a weak acid is a poor conductor as weak acids only partially dissociate into ions. A mixture of a neutral compound and water does not contain free ions necessary for conducting electricity.

3. What is 0.025 mg in mcg?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in a milligram. Therefore, 0.025 mg x 1000 = 25 mcg. This means that the correct answer is A, 25 mcg. Choice B, 250 mcg, is incorrect because it incorrectly multiplies by 10 instead of 1000. Choice C, 2.5 mcg, is incorrect as it inaccurately divides the value by 10. Choice D, 0.25 mcg, is also incorrect as it divides the value by 100 instead of multiplying by 1000.

4. What part of speech is the word 'disappointed' in the sentence 'I was disappointed by the outcome'?

• A. Verb
• B. Noun
• C. Adjective
• D. Adverb

Correct answer: C

Rationale: In the sentence 'I was disappointed by the outcome,' 'disappointed' is used to describe the subject 'I,' indicating its quality. This function classifies 'disappointed' as an adjective. Adjectives modify nouns or pronouns by giving more information about their attributes. Therefore, the correct answer is 'Adjective.' The other choices are incorrect because: - 'Verb' refers to an action word or a state of being, which 'disappointed' is not performing in this sentence. - 'Noun' represents a person, place, thing, or idea, and 'disappointed' does not serve this function in the given sentence. - 'Adverb' modifies verbs, adjectives, or other adverbs, but 'disappointed' is not modifying any of these in the sentence provided.

5. An athlete runs 5 miles in 25 minutes and then changes pace to run the next 3 miles in 15 minutes. Overall, what is the average time in minutes it takes the athlete to run 1 mile?

• A. 7 minutes
• B. 5 minutes
• C. 6.5 minutes
• D. 8.5 minutes

Correct answer: B

Rationale: To find the average time per mile, add the total time taken to cover all miles and then divide by the total miles run. The athlete ran 5 miles in 25 minutes and 3 miles in 15 minutes, totaling 8 miles in 40 minutes. Therefore, the average time per mile is 40 minutes ÷ 8 miles = 5 minutes. Choice A, 7 minutes, is incorrect as it does not reflect the correct average time per mile. Choice C, 6.5 minutes, is incorrect since the calculation is not based on the given information. Choice D, 8.5 minutes, is incorrect as it does not represent the average time per mile for the entire run.
